摘要
考虑浮式装置升沉及横荡运动、立管内流体流动及立管外波浪荷载的共同作用,建立立管振动方程,采用有限元法进行求解,并分析升沉及横荡运动对海洋立管动力响应的影响规律。
Considering the floating system pitching and sway motion, internal fluid flowing and external wave load, the vibration equation of marine riser is established. The finite element method is implemented to solve the matrix equation of equilibrium. Influence rules of pitching and sway motion on the dynamic respose of the marine riser is analyzed.
